Hera and Frigga are two completely different characters. They aren't remotely the same, never have been and never will be. They are two separate, and very different, pantheons. The Norse had their gods, the greeks had theirs, they aren't the same. What are you going to start claiming next, that Hercules is Thor? There are literally tons of comics that prove that is wrong. Even Marvel themselves have separated the Greek Pantheon from the Norse and DC has done the same.

And, Diana isn't even directly related to Hera anyway. Zeus was her father and he is no Odin. Not by a longshot.

And in the comics, I'm pretty sure it would have been mentioned. It never has and never will be.

Thor is not, and will never be, related to Diana.

It's interesting that a hero/villain performs one amazing feat, or use a power they haven't used for 20+ years, and that automatically propels them to a high status despite scans and evidence to the contrary. I don't know what is worse, selective feat picking that has only been done once or twice 20, or more, years ago or ignoring evidence from scans or the lack thereof. We need to stop putting our favorite heroes/villains on pedestals and start putting them where they really belong. But it's evident that people never will because they would rather accuse others of cherry picking feats, when they don't, and being 'morally superior' when they aren't. I guess being honest and as fair as possible only opens one up to being the target of childish accusations and fault finding by those who insist on acting petty and childish. What happened to a good debate between two civil, mature, adults?
